Fraud In The National Climate Assessment (Part 2)

This is the second part of my series exposing fraud in the National Climate Assessment. In the first part, I discussed graph B (US Heat Waves) on their summary page 38. In this part I am discussing graph F (Arctic Sea Ice Extent.)

The Arctic sea ice cover continues the declining trends in the summer maximum and winter minimum extents. In 2018, the summer extent was the sixth lowest and the winter extent was the second lowest in the satellite record (1979-2018).

The claim that satellite record begins in 1979 is incorrect, as the 1990 IPCC report showed NOAA satellite sea ice data since the early 1970s.

satellite observations have been used to map sea-ice extent routinely since the early 1970s. The American Navy Joint Ice Center has produced weekly charts which have been digitised by NOAA.

in 1972-1975 sea-ice extent was significantly less.

NOAA and the National Climate Assessment are hiding the pre-1979 data, probably because extent was “significantly less.” The figures below from the 1990 IPCC report, show the data which is being hidden.

There was a large expansion of Arctic sea ice over the decade from 1971 to 1981.

The 1981 ice edge extended hundreds of miles past the 1971 ice edge. Even more telling is what NSIDC describes as the “1981-2010 median ice edge” – which extends far outside the 1971 edge. It is clear there was a lot less ice in 1971, which is why NOAA, Katharine Hayhoe, Michael Mann and their cohorts at the National Climate Assessment don’t want you to know about it.

It shouldn’t surprise anyone that we have satellite data for Arctic sea ice ice prior to 1979, because we went to the moon in 1969. Here is a beautiful photo of Arctic sea ice taken by Apollo 16 in 1972, seven years before 1979.

In 1965, National Geographic published Arctic satellite imagery – fourteen years before the fake National Climate Assessment start date of 1979.

This satellite imagery of Antarctic sea ice from 1976 shows how detailed the data was, and also shows that there was almost no Antarctic sea ice remaining during the summer – near the peak of the 1970s ice age scare.

But the data hiding story gets even worse. During the decade prior to 1975, Arctic sea ice extent increased by 12% – so extent was even lower prior to 1975. By 1975, Icelandic Ports were blocked with ice for the first time in a century, and climate scientists were warning of a new ice age. So we know that sea ice extent was much lower prior to the 1970s.

The 1985 DOE CO2 report was the predecessor of the IPCC, and shows that extent was very low in the 1950s, and then began to increase rapidly in the 1960s and 1970s – triggering fears of an ice age – as I will document shortly.

If we combine the 1985 DOE graph and the 1990 IPCC graph at the same scale on both axes, it becomes clear why NOAA and the National Climate Assessment start their graphs in 1979. That year was the high point of the last century, and by cherry picking a high point, they can mislead readers into believing sea ice extent is trending linearly down. If they showed the entire series, it would become clear that current sea ice extent and thickness is comparable to the 1950s.

Historical data confirms the warmth and low ice extent of the 1950s. Sixty years ago, the New York Times reported that the polar ice cap had lost 40 percent of its thickness and 12 percent of its area, and were predicting an ice-free Arctic within a generation.

Some scientists estimate that the polar ice pack is 40 per cent thinner and 12 per cent less in area than it was a half-century ago, and that even within the lifetime of our children the Arctic Ocean may open, enabling ships to sail over the North Pole

Although the idea that a solid ice sheet covers the central Arctic has lingered stubbornly in the popular fancy, the northern cap of ice worn by our planet is actually a thin crust—on the whole, only about seven feet thick—over an ocean two miles deep in places.

Evidence is overwhelming the Arctic climate and sea ice is cyclical, and raw, untampered data shows this is true. The NASA graph below of Reykjavik, Iceland temperatures shows why NOAA and the National Climate Assessment start their graphs in 1979 – which was the coldest year on record in Iceland.

Neither extent nor volume of Arctic sea ice shows any trend over the last 12 years. Every year, climate scientists scream it is the hottest year ever, and the ice will soon disappear – but reality provides no evidence to back up their claims,

There is no indication anything has changed in the Arctic, other than normal 60 year cycles – but climate scientists have huge amounts of funding dependent on demonizing CO2 for politicians. So they lie, cheat, hide data and tamper with data.

Twenty thousand years ago, Chicago was covered with a mile of ice. CO2 was much lower than it is today.
